摘要： A reproduction apparatus and method a recording apparatus and method by which two different kinds of data can be reproduced and recorded efficiently are disclosed. When main data are intermittently read in from a recording medium, periods within which reading in of the main data is not performed appear inevitably, and the periods are made use of to read in sub data from the recording medium, thereby allowing synchronized reproduction of the main data and the sub data which relate to the main data. On the other hand, when main data are intermittently written onto a recording medium, periods within which writing of the main data is not performed appear inevitably, and the periods are made use of to write sub data onto the recording medium, thereby allowing parallel recording of the main data and the sub data.

摘要： There is provided a disc recording apparatus for recording digital data by an optical unit in such a manner that time compressed digital data are arranged into a plurality of clusters at an interval of a predetermined number of sectors, a cluster-linking sector having a length longer than an interleaving length is provided at each linking part of each cluster, and the digital data are subsequently interleaved and recorded on a disc-shaped recording medium so that interleaving at the time of data recording on the cluster-by-cluster basis is within the range of the cluster-linking sector. There is also provided a disc reproducing apparatus for reproducing digital data by an optical unit in which playback data are obtained by reproducing record data recorded on a disc-shaped recording medium in such a manner that a cluster-linking sector longer than an interleaving length is provided in a linking section of each cluster composed of a predetermined number of sectors, the resulting data is interleaved and recorded on the disc-shaped recording medium, and the playback data are deinterleaved and freed or the cluster-linking sectors so as to be stored transiently in a storage unit. Playback data are written in the storage unit when the data volume of playback data stored in the storage unit becomes smaller than a predetermined volume to maintain a readout space in the storage unit which is in excess of the predetermined data volume. In this manner, data may be read out continuously from the storage unit at a predetermined rate without interrupting the reproducing operation at the cluster-linking sector of the data recorded on the medium.

摘要： A reproducing apparatus in which a reproduction signal reproduced from a recording medium is temporarily stored in a memory and is thereafter read out, and in which, when the amount of accumulation of the reproduction signal stored in the memory becomes equal to or larger than a predetermined value, a function of at least one section of the reproducing apparatus is inhibited. A part of at least one of a program read out from the memory before the inhibition of the above-mentioned function and other programs before and after the program read out from the memory is previously stored in the memory. Therefore, even if an access to such a program is requested while the function of the related section of the reproducing apparatus is inhibited, the part of the program can be read out to immediately obtain the desired reproduction output.

摘要： A data encoder wherein the outputs of a synchronization data generating means 51, a cluster counter 52, a sector counter 53, a recording data output means 56 and a dummy data generating means 55 are selected by a selector 57 to provide an output. A selector control means 59 is constituted to control the selector 57 to output a data group (cluster) which is one recording unit formed of the predetermined number of sectors in the predetermined format by controlling the selector 57 in a predetermined timing depending on a Link signal based on the sector counter 53 and a count value of the byte counter 60. The processing load shared on a microcomputer, which is controlling the recording operation, can thus be alleviated remarkably.

摘要： A recording apparatus for an optical recording medium having a pregroove and address data includes a recording head apparatus and a controller. The recording head apparatus has an optical head device and records data on the optical recording medium along the pregroove. The optical head device radiates a light beam having an intensity which is enough to record the data on the optical recording medium. The optical head device includes a detector. The controller controls the recording head apparatus and receives an output signal supplied from the detector. The optical head device is controlled to move a recording start point from the previous recording start point by a predetermined value when the controller detects the occurrence of a recording error according to the output signal from the detector and restart recording the data from the moved recording start point on the optical recording medium.

摘要： An apparatus for recording compressed digitized information to an optical disc by reading the digital data into a memory for transient storage. The digital input data thus written into the memory are sequentially read out of the memory and into an encoder at a transfer rate faster than the input transfer rate where the digital data are arranged in discrete clusters of record units including cluster-linking groups such that each record unit can be interleaved independently and without affecting other record units. The interleaved record units are then recorded onto an optical disc. Reproduction of the record units from the optical disk is carried out by reversing the process.

摘要： A high speed dubbing is to be realized with two recording and/or reproducing units for compressed data. To this end, a magneto-optical disc 32 is read by an optical head 33 and compressed data produced via a decoder 41 are delivered to a memory 14 via a switch 37. The data are then delivered to a magnetic head driving circuit 16 via an encoder 15 for direct writing on a magneto-optical disc 2. In this manner, compressed data are directly dubbed without expansion to realize high speed dubbing.

摘要： A recording and/or reproducing apparatus having a memory controller which controls a write-in and read-out operation of data into the memory. When data are recorded on a disc-shaped recording medium by the recording and/or reproducing unit, the memory controller time-divisionally stores into a first storage area of a memory the data which will be recorded on the disc-shaped recording medium by the recording and/or reproducing unit while simultaneously time-divisionally storing into a second storage area of the memory management data for the disc-shaped recording medium which are read out by the recording and/or reproducing unit.
